I'm putting a 261 in my 50 Chevrolet . I purchased a 261 motor . It's complete except for the oil filter there's two passages on the left side of the block very small 1/4 I'm guessing . Where the steel lines would go for the oil filter . I purchased a remote oil filter kit that uses 1/2 pipe fittings . What should I do. I don't want to get crazy and bore out the block
